Notes Density of state and fermi energy in 3-D In three-dimensional (3D) solids, the density of states describes the number of available quantum states per unit energy interval at a given energy level.The free particle SWE in 3-D ...
Notes Relativistic Lagrangian for a charged particle in electromagnetic field. The Lagrangian describes the dynamics of the system and is used in the Lagrangian formulation of classical mechanics to derive the equations of motion of the particle. The principle of ...
